Example of a hierarchical structure
Branch Path through the hierarchy from a parent to a single descendant. In
the figure above, the Support, Rotational Hub, and Ferris Wheel objects
comprise a branch from the root to the leaf objects (the seats).
Leaf Child object that has no children. The lowest object in a branch. In the
figure above, the Seat objects are leaf objects.
Link Connection between a parent and its child. A link transmits position,
rotation, and scale information from parent to child.
Pivot Defines the local center and coordinate system for each object. You can
think of a link as the connection between the pivot of a child object and the
pivot of its parent.
